Abstract (en)

This invention relates to a process for making amines having a high yield weight percent of diethylenetriamine (DETA) and aminoethylethanolamine (AEEA) by condensing an amino compound in the presence of a condensation catalyst selected from a Group IVB metal oxide, a Group VIB metal-containing substance and a promoted condensation catalyst. This invention also relates to an alkyleneamines producers composition rich in DETA and AEEA.
